The sensor boom is now in the flight position and remains so
throughout the sounding.
Now proceed to connect the radiosonde battery.
The timer countdown is different for analog (RS92-KL and RS92-K)
and digital radiosondes (RS92-SGP, RS92-D): For analog
radiosondes, the timer countdown starts on the ground, beginning
when the radiosonde is connected to the Ground Check Set. Therefore,
you have to add some extra time to the timer to be able to activate and
connect the battery and launch the radiosonde. For digital radisondes,
the timer countdown starts from launch detect, and, therefore, no extra
time is required.
